Hello, Ms. 470-635-1, May I Help You?
LEAD: JAY NEWMAN, who just moved to Miami from Philadelphia, found himself digging through the wastebasket recently in search of a discarded letter that might give him a clue to the ZIP code of his new office. No, Mr. Newman wasn't losing his mind. Just his ZIP codes, bank machine personal identification number, cellular phone number, office extensions, not to mention his new home address.
